how to make a parking ground model
Procedurally generated parking spots.

I've made this one just for fun. It probably would be easier just to make mask in some vector app like Inkscape or Illustrator then mix materials by it, but lets stick to pure Blender Cycles solution. This method is from an artist approach, there is a better solution for this shapes for sure but I don't know Node-fu as good to generate them by math.

Setup:



Breakdown:

Stripes.



Mask.



Final thoughts:

Even if it is looking complicated it is just stacking simple things like Gradient texture and Wave texture on top of each other and using this mix as a Mask for textures. I really don't know how to be more precise with it so any questions are welcome and I will extend this answer as needed.
